If you prioritize a high-quality display for HDR gaming and media, as well as color-critical tasks like photo and video editing, the KTC M27P20 Pro with its MiniLED technology will serve you well, offering excellent brightness, contrast, and color accuracy. However, the LG 34GN850B, while less expensive, has a larger screen and an ultra-wide aspect ratio that can enhance productivity and immersion in games and movies, albeit with lower performance in brightness, contrast, and color accuracy. Choose the KTC for top-tier visual quality or opt for the LG if you prefer a wider display and want to save money. Give Feedback

Simon Baker | January 2023
"Gaming and HDR are the two target uses for this screen, and it does generally very well in both. For gaming there are good response times, a single overdrive mode experience for VRR, super low input lag and solid support for latest gen consoles too. The moderately high 160Hz refresh rate provides good motion clarity, and is a nice combination with the high 4K resolution that provides a sharp and crisp image."

"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
